Definitions
- the present invention relates to a mononuclear ruthenium complex having a ruthenium-silicon bond. More specifically, the present invention has catalytic activity in at least one of industrially useful hydrosilylation reaction, hydrogenation reaction, and reduction reaction of a carbonyl compound. It relates to a mononuclear ruthenium complex.
- Hydrosilylation reaction in which a Si-H functional compound is added to a compound having a carbon-carbon double bond or triple bond, is a useful means for synthesizing organosilicon compounds, and is also an industrially important synthesis. It is a reaction.
- Pt, Pd, and Rh compounds are known. Among them, the most frequently used are Pt compounds represented by Speier catalyst and Karstedt catalyst.
- a problem of the reaction using a Pt compound as a catalyst is that, when a Si—H functional compound is added to a terminal olefin, a side reaction occurs in which the olefin undergoes internal rearrangement. In this system, there is no addition reactivity with internal olefins, and unreacted olefins remain in the addition product. Excess olefin must be used. There is also a problem that the selectivity of the ⁇ adduct and the ⁇ adduct is inferior depending on the type of olefin.
- the biggest problem is that the central metals Pt, Pd, and Rh are all extremely expensive noble metal elements, and a metal compound catalyst that can be used at a lower cost is desired. It is being advanced.
- Ru belongs to a noble metal, it is a metal that can be obtained at a relatively low cost, so that a function as a substitute for Pt, Pd, and Rh is required.
- Patent Document 1 a compound having an ⁇ 6 -arene group and having an organopolysiloxane bonded to a central metal Ru or a vinylsiloxane coordinated has been reported (Patent Document 1). Although this compound has been shown to be effective for the addition reaction of methylhydrogenpolysiloxane and methylvinylpolysiloxane, the yield is low in the reaction at 120 ° C, and 160 ° C in order to obtain a high yield. The reaction must be carried out at high temperatures. In addition, in Patent Document 1, many patents relating to Ru catalysts are cited as prior documents (Patent Documents 2 to 6). I can't say that.
- Non-Patent Document 2 discloses a mononuclear ruthenium complex effective for the hydrogenation reaction of a tetrasubstituted olefin, which is said to have a low reaction yield, but it has a low turnover number and can be used under high pressure conditions. Reaction conditions are required.
- a method of reducing the carbonyl compound there is a method of using hydrogen in the presence of a hydrogen compound of aluminum or boron or a noble metal catalyst.
- a hydrogen compound of aluminum or boron or a noble metal catalyst there is a method of using hydrogen in the presence of a hydrogen compound of aluminum or boron or a noble metal catalyst.
- ketones and aldehydes are known to be stable and easy-to-handle hydride reagents and precious metal catalysts for hydrogenation that can proceed under mild conditions.
- carboxylic acid derivatives such as esters and amides are known.
- a method using a strong reducing agent such as lithium aluminum hydride or borane is mainly used (Non-patent Document 3).
- these reducing agents are ignitable and water-inhibiting substances, they are difficult to handle.
- Non-patent Documents 8 and 9 As a mononuclear complex compound having a ⁇ bond between ruthenium and silicon, a bivalent complex having a six-electron ligand (Non-patent Documents 8 and 9), a tetravalent complex having a two-electron ligand (non-patent Documents 10 and 11), tetravalent complexes having a six-electron ligand (Non-Patent Documents 9 and 12), divalent complexes having a thiourea group on silicon (Non-Patent Document 13), two having a halogen on silicon Known are a valence complex (Non-Patent Document 14), an anion complex (Non-Patent Document 15), and a bivalent complex (Non-Patent Documents 15 and 16) having an agotic Si—H ligand as a dielectron ligand Yes.
- Non-Patent Documents 16 and 17 bivalent complexes that have no ⁇ bond between ruthenium and silicon and have an aggressive Si—H ligand as a two-electron ligand. Furthermore, as a mononuclear complex compound having isonitrile as a two-electron ligand, a divalent complex having a ⁇ bond between two ruthenium and silicon, CO, and a halogen group on silicon (Non-patent Document 18), 2 Bivalent complex having a ⁇ bond between one ruthenium and silicon and CO (Non-patent Document 19), Bivalent complex having a ⁇ bond between one ruthenium and silicon and CO (Non-patent Document 20), 2 Divalent complex having one ⁇ bond between ruthenium and silicon and a halogen group on silicon (Non-patent Document 21), and divalent complex having only one ⁇ bond between ruthenium and silicon (Non-patent Document 22) In addition, a divalent complex having no ⁇ bond
- the ruthenium complexes disclosed therein may have catalytic activity for hydrosilylation reaction, olefin hydrogen reaction, and / or carbonyl compound reduction reaction. It does not suggest any gender.
- a reaction example using a ruthenium complex as a catalyst an addition reaction between ethylene and dimethylchlorosilane (Non-patent Document 23) has been reported, but its reactivity and selectivity are low.

Abstract
Description
このヒドロシリル化反応の触媒としては、Pt、Pd、Rh化合物が知られており、その中でも最も多く用いられているものはSpeier触媒、Karstedt触媒に代表されるPt化合物である。 Hydrosilylation reaction, in which a Si-H functional compound is added to a compound having a carbon-carbon double bond or triple bond, is a useful means for synthesizing organosilicon compounds, and is also an industrially important synthesis. It is a reaction.
As catalysts for this hydrosilylation reaction, Pt, Pd, and Rh compounds are known. Among them, the most frequently used are Pt compounds represented by Speier catalyst and Karstedt catalyst.
また、オレフィンの種類により、α付加体とβ付加体の選択性が劣るという問題もある。 A problem of the reaction using a Pt compound as a catalyst is that, when a Si—H functional compound is added to a terminal olefin, a side reaction occurs in which the olefin undergoes internal rearrangement. In this system, there is no addition reactivity with internal olefins, and unreacted olefins remain in the addition product. Excess olefin must be used.
There is also a problem that the selectivity of the α adduct and the β adduct is inferior depending on the type of olefin.
また、この特許文献1には先行文献としてRu触媒に関する多くの特許が引用されているが(特許文献2~6)、反応性、選択性、経済性の観点からいずれも貴金属元素系触媒に勝っているとは言えない。 As for this Ru compound, a compound having an η 6 -arene group and having an organopolysiloxane bonded to a central metal Ru or a vinylsiloxane coordinated has been reported (Patent Document 1). Although this compound has been shown to be effective for the addition reaction of methylhydrogenpolysiloxane and methylvinylpolysiloxane, the yield is low in the reaction at 120 ° C, and 160 ° C in order to obtain a high yield. The reaction must be carried out at high temperatures.

また、非特許文献2には反応収率が低いとされている4置換オレフィンの水素化反応に有効な単核ルテニウム錯体が開示されているが、ターンオーバー数が低く、また高圧条件下での反応条件が必要である。 On the other hand, the hydrogenation reaction of olefins is also an industrially important reaction. However, noble metals such as Pt, Pd, and Rh are used in conventional catalysts, and the use of inexpensive ruthenium is desired among the noble metals. For example, there are those using a trinuclear ruthenium complex as shown in

空気中で安定かつ取り扱いが容易なヒドロシラン化合物、メチルハイドロジェンポリシロキサンを還元剤として使用する方法が数多く報告されているが、反応には強い酸またはルイス酸の添加や、高価な貴金属触媒を必要とする。最近、比較的安価なルテニウムを触媒とするカルボニル化合物の還元反応が報告されており、そのうちの一部は、従来法では過酷な条件を必要とするアミドの還元反応に適用した例も出ている。具体的なルテニウム触媒の例として非特許文献4~7が挙げられるが、より高いターンオーバー数を示す高活性触媒が望まれている。 As a method of reducing the carbonyl compound, there is a method of using hydrogen in the presence of a hydrogen compound of aluminum or boron or a noble metal catalyst. Among carbonyl compounds, ketones and aldehydes are known to be stable and easy-to-handle hydride reagents and precious metal catalysts for hydrogenation that can proceed under mild conditions. However, carboxylic acid derivatives such as esters and amides are known. For the reduction, a method using a strong reducing agent such as lithium aluminum hydride or borane is mainly used (Non-patent Document 3). However, since these reducing agents are ignitable and water-inhibiting substances, they are difficult to handle. Also, care should be taken when removing the reacted aluminum or boron compound from the target product. In addition, reduction of carboxylic acid derivatives requires high temperature and pressure hydrogen.
Many methods have been reported that use a hydrosilane compound, methyl hydrogen polysiloxane, which is stable in air and easy to handle, as a reducing agent, but the reaction requires the addition of a strong acid or Lewis acid, and an expensive noble metal catalyst. And Recently, relatively inexpensive ruthenium-catalyzed reduction reactions of carbonyl compounds have been reported, some of which have been applied to amide reduction reactions that require harsh conditions in the conventional method. . Specific examples of the ruthenium catalyst include

一方、ルテニウム錯体を触媒に用いた反応例としては、エチレンとジメチルクロロシランとの付加反応(非特許文献23)が報告されているが、その反応性と選択性は低いものである。
